Marine Ecosystem Research At The Weddell Sea Ice Edge: The Ameriez Program, Walker O. Smith Jr., Dl Garrison

VIMS Articles

The explorers and naturalists who first visited Antarctica were struck by the large numbers of whales, seals and seabirds in such a harsh environment (summarized in Everson, 1977). Scientific expeditions in the twentieth century confirmed these observations, and also established that an even greater abundance of many different trophic levels occurred at the ice edge. Hart (1942) noted that phytoplankton were more abundant near the ice edge mad suggested that there was a distinct ice-edge flora, and Marr (1962) noted that krill (Euphausia superba) were concentrated at the interface between pack ice and open water. Routh (1949) observed …

Ancient Channels Of The Susquehanna River Beneath Chesapeake Bay And The Delmarva Peninsula, Steven M. Colman, Jeffrey P. Halka, C. Hobbs, Robert B. Mixon, David S. Foster

VIMS Articles

Three generations of the ancestral Susquehanna River system have been mapped beneath Chesapeake Bay and the southern Delmarva Peninsula. Closely spaced seismic reflection profiles in the bay and boreholes in the bay and on the southern Delmarva Peninsula allow detailed reconstruction of each paleochannel system. The channel systems were formed during glacial low sea-level stands, and each contains a channel-fill sequence that records the subsequent transgression. The trunk channels of each system are 2 to 4 km wide and are incised 30 to SO m into underlying strata; they have irregular longitudinal profiles and very low gradients within the Chesapeake …

Pliocene And Pleistocene Depositional Environments On The York-James Peninsula, Virginia; A Field Guidebook, Gerald H. Johnson, Carl H. Hobbs Iii

Reports

The late Cenozoic deposits of southeastern Virginia represent a wide variety of depositional environments and record numerous marine transgressions. The formations range in age from Miocene to Holocene. This fieldguide provides an opportunity to visit and sample highly fossilferous marine bay and fluvial-estuarine sediments exposed in river bluffs and borrow pits on the York-James Peninsula.

Chesapeake Bay Wave Climate : Thimble Shoals Wave Station, Report And Summary Of Wave Observations, September 27, 1988 Through October 17, 1989, John D. Boon, S. M. Kimball, K. D. Suh, D. A. Hepworth

Reports

The Virginia Institute of Marine Science, in cooperation with the Virginia Department of Conservation and Recreation, Division of Soil and Water Conservation, has identified as one of its major goals the systematic study of hydrodynamic processes that affect recreational, shoreline and benthic resources in the coastal zone of the Commonwealth. In pursuit of that goal, a long-term study of the wave climate in the Virginia portion of Chesapeake Bay was initiated in 1988 with support from the National Oceanographic and Atmospheric Administration through the Coastal Zone Management Program administered by the Virginia Council on the Environment (Grant Ho. HA88AA-D-CZ092). Past …

Geological And Benthic Evaluation Of Sand Resources In The Lower Chesapeake Bay, Report 2, Tail Of The Horseshoe : Final Report V.1, Carl C. Hobbs Iii, Linda C. Schaffner

Reports

This is the second of two reports concerning the resources of sand in the lower portions of Chesapeake Bay. The first, Geotechnical and Benthic Evaluation of Sand Resources in the Lower Chesapeake Bay (Kimball and others, 1989), presents a study of the resources in Thimble Shoal. The present work is a study of the area known as Tail of the Horseshoe which is just east of Thimble Shoal (Figure 1). The deposits of sand described in this report will be of most interest to the communities of Norfolk and Virginia Beach.

A Survey Of Compensatory Mitigation Within The Tidal Wetlands Of Virginia, Thomas A. Barnard, Pamela Mason

Reports

This study has as its primary purpose an examination of how compensatory mitigation has worked as a wetlands management tool to date in Virginia (i.e. how well theory has been put into practice). Our approach was to look at the overall use of compensation in coastal Virginia based on regulatory records and to examine as many existing created wetlands as possible within the tidal area of the state to determine how closely these projects have come, collectively, to fulfilling the compensatory goal of wetland replacement. Secondary objectives includes an examination of the literature regarding wetland compensation concept evaluation and to …

Analysis Of Organic Pollutants In Sediments And Blue Crab (Callinectes Sapidus) Tissues : Final Report To Virginia State Water Control Board, John Greaves

Reports

The Elizabeth River is a highly industrialized waterway that divides the cities of Norfolk and Portsmouth at its confluence with the lower Chesapeake Bay. It is home to the largest Naval base on the East Coast, numerous ship repair facilities, bulk and containerized cargo facilities, industrial and urban activities and wood creosoting (preserving) operations (all except one have been abandoned). This degree of industrialization has resulted in the pollution of the river, with high concentrations of polynuclear aromatic hydrocarbons (PAH, Bieri et al., 1986). A major contributor to the pollution problem has been the wood processing industry which, due to …

Dissolved Oxygen Conditions In The Machipongo River System Near Willis Wharf, Va, Bruce Neilson, Nancy Wilson

Reports

Water temperature, salinity, and dissolved oxygen concentrations were monitored at two sites in the Machipongo River system in early summer of 1989 and late summer of 1990. The two study sites have been designated as "Willis Wharf" and "Quinby." The Machipongo River system and the two sampling locations are shown in Figure 1.

Single And Double Nucleophilic-Addition To Coordinated Pi-Hydrocarbons - Manganese-Mediated Functionalization Of Arenes, Robert D. Pike, D. A. Sweigart

Arts & Sciences Articles

A range of carbon-donor nucleophiles add to the arene ring in (arene)Mn(CO)2L+ cations to give neutral cyclohexadienyl complexes that liberate monofunctionalized arenes upon oxidative removal of the metal. Treatment of the cyclohexadienyl complexes with the nitrosonium salt NOPF6 affords cationic metal nitrosyl complexes that are attacked by a second nucleophile to give cis- and trans-difunctionalized 1,3-cyclohexadienes. When the metal center is chiral, this procedure provides a route to enantiomerically pure cyclohexadienes. 1. Introduction 2. Mechanism of Nucleophilic Addition 3. Single Nucleophilic Addition 4.

Cataract Occurrence In Micropogonia Furnieri (Desmarest, 1822) In The Area Between Capes Frio And Torres (23° S And 29° S), Brazil : Investigation Of Causes And Electrophoretic Studies Of Total Proteins Of The Eye Lenses, Anna Emila A. De M. Vazzoler, Van Ngan Phan

Reports

The frequency and distribution of these specimens were analysed and the electrophoretic patterns of soluble eye-lens proteins were determined. This cataract is not of parasitic origin and was rare in specimens from the coastal area. In the lagunar region it occurs mainly in specimens of the River Baguacu from April to November.
